The Urban Dictionary Mug

1) To go down a never ending tunnel with many twists and turns on the internet, never truly arriving at a final destination, yet just finding more tunnels. Clicking one link, then finding another on that page, then clicking another link on that page, which gives you the idea to search for something, and the process repeats.

2) Nonsensical process of getting from Point A to Point B with no clear route (and often no recollection) on how one got there.

1) "Josh always goes down the rabbit hole, he started by looking at a news website and reading about Global Warming, but twenty minutes later he's clicked his way to watching youtube videos of monkey's masturbating to sad music"

2) "Team C started out as a unit designation, but after two years of going down the rabbit hole the C stood for chaos, and Team was just a group of guys who wanted to make it home without a rabbit in their asses at the end of the day"

The Urban Dictionary Mug

It comes from Alice in Wonderland where she fell down the Rabbit Hole into some bizarre shit (trippy stuff from the 70s). Therefore, it is commonly used as an expression or euphuism for a portal to bizzarro world/significantly strange happenings/extremely surreal situations, etc.

Dude A: "I was drinking one minute and the next thing I knew I was in a corn field, buck naked, covered in body paint with my genitals pierced singing Christmas songs..."
